Abstract

Background: Malnutrition indices and muscle mass and strength in the elderly are poorly investigated. Moreover, malnutrition seems to be 1 of the more important factors in the cause of sarcopenia. The presence of sarcopenia and its relationship with malnutrition indices were studied in noninstitutionalized elderly people who underwent Comprehensive Geriatric Assessment (CGA). Methods: A total of 473 elderly subjects (mean age, 80.9 ± 6.6 years) admitted to CGA were studied. Malnutrition risk was evaluated with Mini Nutritional Assessment (MNA) score, whereas muscle mass and muscle strength were evaluated by bioimpedentiometry and hand grip, respectively. Sarcopenia was assessed as indicated in the European Working Group on Sarcopenia in Older People (EWGSOP) consensus. Results: Overall prevalence of sarcopenia was 13.1%, and it increased from 6.1% to 31.4% as MNA decreased (P <.001). MNA score was lower in elderly subjects with sarcopenia (15.4 ± 4.2) than without sarcopenia (22.0 ± 4.0) (P =.024). Linear regression analysis showed that MNA score is linearly related both with muscle mass (r = 0.72; P <.001) and strength (r = 0.42; P <.001). Multivariate analysis, adjusted for several confounding variables including comorbidity and disability, confirmed these results. Conclusions: MNA score is low in noninstitutionalized elderly subjects with sarcopenia, and it is linearly related to muscle mass and muscle strength. These data indicate that MNA score, when evaluated with muscle mass and strength, may recognize elderly subjects with sarcopenia.
